    Soy Food Intake and Breast Cancer Survival.
    Xiao Ou Shu et al.
    JAMA Vol. 302 No. 22, December 9, 2009; 302(22):2437-2443.

    Results During the median follow-up of 3.9 years (range, 0.5-6.2 years), 444 deaths and 534 recurrences or breast cancer-related deaths were documented in 5033 surgically treated breast cancer patients. Soy food intake, as measured by either soy protein or soy isoflavone intake, was inversely associated with mortality and recurrence. The hazard ratio associated with the highest quartile of soy protein intake was 0.71 (95% confidence interval [CI], 0.54-0.92) for total mortality and 0.68 (95% CI, 0.54-0.87) for recurrence compared with the lowest quartile of intake. The multivariate-adjusted 4-year mortality rates were 10.3% and 7.4%, and the 4-year recurrence rates were 11.2% and 8.0%, respectively, for women in the lowest and highest quartiles of soy protein intake. The inverse association was evident among women with either estrogen receptor-positive or -negative breast cancer and was present in both users and nonusers of tamoxifen.

    Conclusion Among women with breast cancer, soy food consumption was significantly associated with decreased risk of death and recurrence.

    PMID: 19921445

    Our results suggest that a diagnosis of NMSC is not a surrogate for adequate 25(OH)D levels or increased UV exposure, and high 25(OH)D levels may be associated with a reduced risk of NMSC.

    Israeli 'cancer shift' over heart disease mortality may be led by greater risk in women with high intake of n-6 fatty acids.
    Shapira N.
    Eur J Cancer Prev. 2007 Oct;16(5):486-94.
    PMID: 17923822
    doi: 10.1097/CEJ.0b013e3280145b6d

    Population studies of Israeli Jews, Arabs, and women support the association of high n-6 polyunsaturated fatty acid intake with increased cancer risk and higher female sensitivity. Research findings suggest that gender and sex hormones may influence n-6 polyunsaturated fatty acid metabolism and carcinogenesis. This appears to be the first time gender has been proposed to modulate national cancer epidemiology, suggesting implications for differential nutritional prevention, warranting further research.

    Millen AE, Pettinger M, Freudenheim JL, Langer RD, Rosenberg CA,
    Mossavar-Rahmani Y, Duffy CM, Lane DS, McTiernan A, Kuller LH, Lopez AM, Wactawski-Wende J.
    Cancer Epidemiol Biomarkers Prev. 2009 Feb;18(2):495-507. Epub 2009 Feb 3.
    PMID: 19190147
    doi: 10.1158/1055-9965.EPI-08-0652

    In conclusion, region of residence and geographic solar irradiance are not consistently related to risk of breast cancer and may not be sufficient proxy measures for sunlight/vitamin D exposure. The observed association between time spent outside and breast cancer risk support the hypothesis that vitamin D may protect against breast cancer.

    A multicountry ecologic study of risk and risk reduction factors for prostate cancer mortality.
    Grant WB.
    Eur Urol. 2004 Mar;45(3):271-9.
    PMID: 15036670

    CONCLUSIONS: These results are consistent with insulin-like growth factor-I (IGF-I), being an important risk factor for prostate cancer, with alcohol and calcium being less important risk factors, and with allium family vegetables, and, to a lesser extent, vitamin D being important risk reduction factors. These results should provide guidance for additional studies on dietary and environmental links to prostate cancer.

    Association between plasma 25-hydroxyvitamin D and breast cancer risk.
    Crew KD, Gammon MD, Steck SE, Hershman DL, Cremers S, Dworakowski E, Shane E, Terry MB, Desai M, Teitelbaum SL, Neugut AI, Santella RM.
    Cancer Prev Res (Phila Pa). 2009 Jun;2(6):598-604. Epub 2009 May 26.
    PMID: 19470790

    In summary, these results add to a growing body of evidence that adequate vitamin D stores may prevent breast cancer development. Whereas circulating 25-OHD levels of >32 ng/mL are associated with normal bone mineral metabolism, our data suggest that the optimal level for breast cancer prevention is ≥40 ng/mL. Well-designed clinical trials are urgently needed to determine whether vitamin D supplementation is effective for breast cancer chemoprevention.

    PMID: 18756015
    doi:10.1093/aje/kwn198

    This study suggests that vitamin D is associated with a reduced risk of breast cancer regardless of ER/PR status of the tumor. Future studies with a larger number of receptor-negative and mixed tumors are required.

    Serum 25-hydroxyvitamin D and colon cancer: eight-year prospective study.
    Garland CF, Comstock GW, Garland FC, Helsing KJ, Shaw EK, Gorham ED.
    Lancet. 1989 Nov 18;2(8673):1176-8.
    PMID: 2572900

    Blood samples taken in 1974 in Washington County, Maryland, from 25 620 volunteers were used to investigate the relation of serum 25-hydroxyvitamin D (25-OHD) with subsequent risk of getting colon cancer. 34 cases of colon cancer diagnosed between August, 1975, and January, 1983, were matched to 67 controls by age, race, sex, and month blood was taken. Risk of colon cancer was reduced by 75% in the third quintile (27-32 ng/ml) and by 80% in the fourth quintile (33-41 ng/ml) of serum 25-OHD. Risk of getting colon cancer decreased three-fold in people with a serum 25-OHD concentration of 20 ng/ml or more. The results are consistent with a protective effect of serum 25-OHD on colon cancer.

    Prospective study of predictors of vitamin D status and cancer incidence and mortality in men.
    Giovannucci E, Liu Y, Rimm EB, Hollis BW, Fuchs CS, Stampfer MJ, Willett WC.
    J Natl Cancer Inst. 2006 Apr 5;98(7):451-9.
    PMID: 16595781
    doi:10.1093/jnci/djj101

    Conclusions: Low levels of vitamin D may be associated with increased cancer incidence and mortality in men, particularly for digestive-system cancers. The vitamin D supplementation necessary to achieve a 25(OH)D increment of 25 nmol/L may be at least 1500 IU/day.

  •  
    The association of solar ultraviolet B (UVB) with reducing risk of cancer: multifactorial ecologic analysis of geographic variation in age-adjusted cancer mortality rates.
    Grant WB, Garland CF.
    Anticancer Res. 2006 Jul-Aug;26(4A):2687-99.
    PMID: 16886679

    CONCLUSION: These results provide additional support for the hypothesis that solar UVB, through photosynthesis of vitamin D, is inversely-associated with cancer mortality rates, and that various other cancer risk-modifying factors do not detract from this link. It is thought that sun avoidance practices after 1980, along with improved cancer treatment, led to reduced associations in the latter period. The results regarding solar UVB should be studied further with additional observational and intervention studies of vitamin D indices and cancer incidence, mortality and survival rates.

    Are sunlight deprivation and influenza epidemics associated with the onset of acute leukemia?
    Timonen T, Näyhä S, Koskela T, Pukkala E.
    Haematologica. 2007 Nov;92(11):1553-6.
    PMID: 18024404
    doi:10.3324/haematol.10799

    Month of diagnosis of 7,423 cases of acute leukemia (AL) in Finland during 1964-2003 were linked with data on influenza and solar radiation. Acute myeloblastic leukemia (AML) showed the highest risk in the dark season. During the light season, the incidence decreased by 58% (95% confidence interval, 16-79%) per 1,000 kJ/m2/d increase of solar radiation. Independent of solar radiation, AML increased by 9% (95% confidence interval, 0-19%) during influenza epidemics. Reoccurring at the same time annually, darkness-related vitamin D deficiency and influenza could cause successive and co-operative mutations leading to AL with a short latency.

    Vitamin D status and the risk of lung cancer: a cohort study in Finland.
    Kilkkinen A, Knekt P, Heliövaara M, Rissanen H, Marniemi J, Hakulinen T, Aromaa A.
    Cancer Epidemiol Biomarkers Prev. 2008 Nov;17(11):3274-8.
    PMID: 18990771v

    In conclusion, although there was no overall association between vitamin D and lung cancer risk, women and young participants with a higher level of vitamin D were observed to have a lower lung cancer risk. Although experimental data support the suppressing effect of vitamin D on the development of lung cancer, large epidemiologic studies from different populations with repeated measurements of vitamin D are warranted to confirm this finding.
